Heat pump vs Furnace in San Juan County, New Mexico
When a heat pump makes sense
A heat pump makes sense if you want air conditioning and heat from one system and you're willing to pay more to run it through the winter. Look at a cold-climate model, not a standard one. Standard heat pumps lose heating power once temperatures drop, and your winter nights here average 20°F, cold enough to matter for eight months of the year.
When a furnace makes sense
A furnace is the right call for most homes here. Natural gas costs at least 40% less than a heat pump to run at New Mexico prices, and with winter nights averaging 20°F for eight months a year, that cost difference adds up. It's also why 63% of homes in the county already heat with gas. The tradeoff is that a furnace only heats, so you'll need a separate system for summer cooling.

Furnace wins in San Juan County.
Gas heat runs at least 40% cheaper here than a heat pump, and with winter nights averaging 20°F, that adds up fast.
If your home has no gas line to it, a cold-climate heat pump will still heat it through those 20°F nights and cool it in summer too.
